10 steps? Errrrr… does it permit setting the sequence length shorter than 10, for those of us who aren’t that proggy and would rather play in common time? (Meaning, 8 steps would be far more sensible.)

I should have continued on to say that calling analogWrite(redLedPin, 128); would (due to PWM) reverse-bias the red LED 50% of the time, causing it to be (roughly) half as bright. This is because when a diode is reverse-biased, no current flows through it. Makes sense?
